I'm joining the thread so I can pay attention to the knowledge here.
AR's are great. I often "borrow" and shoot a 375 socom.
The 458 is ok, but for some reason the 375 just hits every target.
Half dollar size hole on a 1000 lb hog at 200 yards.
Of course, I'm also super impressed by the 204. Also prefer it on the ar frame. Amazing bullet. 4K plus a second. That thing reach's out and touch's.
Mostly, I swear by the 44 ruger super red hawk. Both long and short. Always fires. Ultimate reliability.
